Abstract

Abstract: The γ-ray radiation technique combined with hydrothermal crystallization was firstly used to prepare ultrafine metallic particles of An,Cu and Au-Cu alloy.Particle size for Au in average is about 10 nm.The morphologies were observed by TEM.The nucleation mechanism of metal particles and their stability are discussed.

Key words: radiation chemistry, ultrafine powder hydrothermal technique, Cu, Au, Cu-Al alloy
